     The carbon is solid solution strengthening effect of the most obvious element in the alloy steel 4140 steel. With the increase of carbon content, the strength of the steel is increased, the plasticity and toughness is decreased in a short period of time. On the 4140 steel, the carbon content of the rise will accelerate the spheroidizing of carbides and gathered speed, accelerating the redistribution of alloying elements, reduce steel weldability, corrosion resistance and oxidation resistance. So heat resistant steel generally want to reduce the carbon content, but the carbon content is too low, the strength of the 4140 steel will reduce.
